pH Tester

Introduction

An ORP tester measures oxidation-reduction potential in liquids. It is widely used in water treatment, disinfection control, and environmental analysis.

Standards

GB/T 11165-2005-Laboratory pH meter

USP General Chapter <791>-pH

IEC 60746-2:2003-Expression of performance of electrochemical analyzers-Part 2: pH value

Complies with the above standards, but is not limited to them.

Features

1. Multi-parameter capability consolidates several bench measurements.

2. Data hold, logging and export support records and reports.

3. Replaceable electrodes and probes suit different parameters.

4. Water-resistant, portable design suits field and bench use.

5. Electrode diagnostics indicate when maintenance is needed.

FAQ

What are the main applications of the pH Tester?

The pH Tester is used to measure electrochemical properties such as pH, conductivity, dissolved oxygen or ion concentration. It supports water treatment, environmental monitoring, chemical, pharmaceutical, food and research laboratories.

Which standards and regulations apply to the pH Tester?

The meter is designed with reference to IEC 61010 electrical safety and relevant GB/T standards for electrochemical measurement, with procedures following applicable standard methods and buffer systems. Compliance documentation can be provided on request.

How long is the warranty period?

We provide a 12-month limited warranty on the instrument and its key working parts. Consumables, accessories and parts subject to normal wear are excluded, as is damage caused by incorrect operation or maintenance. An extended service plan is available on request.

Will staff need special training?

Day-to-day use is simple, with clear prompts and pre-set functions reducing manual steps. New operators should review the manual and complete a short familiarisation. Our technical team offers remote support during the first runs.

What is the typical lead time for order delivery?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Is calibration included?

The unit is calibrated and tested before delivery. For ongoing accuracy, verify it against traceable reference standards every 6 to 12 months, or according to the laboratory quality schedule. We can arrange calibration service and certificates where required.

Are consumables and spare parts easy to obtain?

Common consumables and standard spare parts are available through our service channel and are not locked to proprietary formats. Quote the model and serial number when ordering so the correct items are supplied. Lead time for standard parts is usually short.

Are options or configurations available?

A range of options is available to match the application, such as alternative settings, fittings, data outputs or power supply. We confirm each option and its effect on price and schedule up front. Larger custom builds can be discussed.

Do you provide on-site installation?

Standard installation is straightforward and supported by the manual and start-up documentation. Our technical team can guide staff remotely through checks and validation. On-site commissioning is available as a quoted service.

What maintenance and safety points matter?

Do not let the electrode dry out, measure outside the rated range or store probes incorrectly. Rinse and condition electrodes and calibrate regularly. Follow the operating instructions.
